What are water treatment chemicals?

Main Uses:

Remove impurities & heavy metalsTo make water cleaner and safer.
Disinfect & sanitizePrevents harmful bacteria and viruses.
Adjust water pHStabilize pH, reduce equipment corrosion.
Anti-scale & anti-corrosionProtecting pipeline systems, boilers, and water filtration systems.

📌 Practical examples:

In pool water treatment, chemicals like Javen (NaClO), Calcium hypochlorite tablets (Ca(OCl)2) helps disinfect, kill moss and algae.
In industrial wastewater, Ferric Chloride, Polyaluminum Chloride help precipitate and remove suspended solids.

The importance of water treatment chemicals: 

Protect healthWastewater treatment chemicals and household water treatment chemicals play an important role in protecting health by removing bacteria, viruses, and harmful substances.
Environmental protectionAt the same time, they help prevent environmental pollution and minimize negative impacts on ecosystems.

Common water treatment chemicals

Wastewater treatment chemicals Wastewater treatment chemicals such as aluminum sulfate (Al2(SO4)3), ferric chloride (FeCl3), and pH adjusters play a crucial role in removing organic matter, heavy metals, and suspended particles, ensuring that wastewater meets standards before being discharged into the environment.

Aluminum sulfateCoagulation of small particles into larger flocculent masses that settle easily.
Iron chlorideIron(III) chloride)Effective in treating wastewater with low pH.
Sodium bisulfiteRemove residual chlorine from wastewater before discharging it into the environment.
Oxidizing agentH2O2, Potassium permanganateDegradation of recalcitrant organic compounds.
pH adjusterSodium hydroxide, Hydrochloric acid)Stabilize pH to optimize treatment efficiency.

Pool water treatment chemicals Pool water needs to be treated regularly to maintain cleanliness and safety for users. 

Granules (Calcium hypochlorite)Strong disinfectant, sterilizes, eliminates microorganisms.
Cyanuric acid (C3N3O3H3)Chlorine stabilizer, limits decomposition from sunlight.
pH adjusterAs HCL will lower the pH when the water is too alkaline, Sodium carbonate (Na2CO3) will increase pH when water is too acidic.

AlgaecideLimit algae growth in swimming pools.

Water treatment chemicals for domestic use Drinking water needs to meet high standards for cleanliness and safety.
Ozone (O3)Removes color, odor, disinfects effectively, and does not produce harmful byproducts.
Calcium hydroxide (Ca(OH)2)Remove acids and heavy metals.
Sodium hypochlorite (NaClO)Commonly used in water treatment plants.

Boiler water treatment chemicals Help protect the system from scale and corrosion

Scale remover (Citric acid, phosphoric acid)Remove scaling in boiler systems.
Dissolved Oxygen Scavenger (Sodium sulfite)Prevents oxidation corrosion.

Industrial water treatment chemicals Ensure water quality meets production requirements

EDTAWater softening, removal of calcium and magnesium ions.
Hydrogen peroxide (H2O2)Strong sterilization, decomposes organic compounds.
RO membrane cleanerRemove scale and bacteria adhering to the membrane surface.

Water treatment chemicals
Choosing the right chemical depends on Type of water to be treated and pollution level.

How to Choose Effective Chemicals:

Industrial wastewater treatmentSelect PAC or FeCl3 coagulate, precipitate.
Pool water treatmentUse Calcium hypochlorite tablets to disinfect.
Household water treatmentUse NaClO (Javen) or O3 to disinfect.
Boiler System ProtectionNeed Antiscalant (Na3PO4, citric acid).

📌 Notes for use:

Read the instructions carefully before use.
Measure correctly to avoid harming your health.
Store in a dry place, away from direct sunlight.

The Role and Applications of Water Treatment Chemicals

Role: 

Water treatment chemicals play a vital role in improving water quality, removing bacteria, impurities, and heavy metals, protecting human health and the environment. They help extend equipment life, prevent scaling and corrosion, and meet safety standards, while also effectively supporting industrial, domestic, and agricultural sectors.

Application 

Remove impurities and disinfectChemicals that help remove bacteria, viruses, heavy metals, and organic compounds, ensuring clean and safe water for living and production.
Adjust pH and stabilize waterChemicals such as NaOH or H2SO4 are used to adjust pH, improve treatment efficiency, and protect equipment.
Prevent scale and corrosionAntiscalants and dissolved oxygen scavengers protect pipelines, boilers, and industrial equipment, reducing maintenance costs.
Wastewater reuseWastewater treatment for reuse in production, irrigation, or other purposes, reducing pressure on natural water sources and conserving resources.
Environmental protectionWastewater treatment meets standards before discharging into the environment, minimizing water source pollution and protecting the ecosystem.
Industrial production supportIndustries such as food, pharmaceuticals, chemicals, and energy use water treatment chemicals to ensure clean water sources and meet strict production standards.

Legal standards for water treatment

QCVN 40:2011/MONRENational technical regulation on industrial wastewater.
QCVN 01:2009/BYTStandards for clean water for domestic use.
ISO 14001International standard for environmental management.

Instructions for using and storing chemicals

UseBefore use, you need to Read the user manual carefully to understand how to handle it safely and effectively. Chemicals must be Dilute to the correct ratio according to the manufacturer's recommendations to ensure processing performance and avoid waste. At the same time, regular monitoring of water quality throughout the treatment process is crucial for timely adjustments, ensuring optimal and safe results for the system.
Storage:

Store in a cool, dry place, away from direct sunlight.
Seal the packaging tightly after each use.
Keep out of reach of children and away from heat sources.
